ARTICLE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 515,539, dated February27, 1894:.

Original application filed June 7, 1888, $erial No. 276,392. Divided andthis application filed April 12, 1893. Serial lio- 470,139 (No model.)

To all whom it may concern.-

Be it known that I, ALBERT STEFFIN, of New Bedford, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovements in Articles of Glassware;

and I do hereby declare the following to be av full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improved articles of glassware and is a divisionof my application filed June 7, 1888, Serial No. 27 6,392.

My invention consists of an article of glassware having its surfaceornamented or decorated and divided into sections by opaque dividinglines the latter projecting out from the surface of the article to giveit the appearance of being constructed in sections of stained glass.

In the accompanying drawings, Figure l is a view of a lamp shade thesurface of which is divided up into segments and Fig. 2 is a viewshowing the completed shade.

While the invention is designed for use on all articles of glass-ware,for the purpose of illustration I have shown the invention applied to alamp shade, but I would have it understood that its application or useis not confined to any particular line of goods but can be applied toany and all glass articles. The shade or other article is divided intocolored segments A, B, O, D, by lines I) of distinct color joining andconnecting at given points around centers on which are also colored asthough held by frame 11. In Fig. 2 is shown a similar shade with theaddition of a pattern f formed on the various colored segments, andcolored in contrasting colors to the groundwork.

To carry out my invention I take an article of glassware which maybe ofany desired form. After thoroughly cleansing the surface I proceed todecorate it with colors known to the art as mineral or vitrifiable,prepared in the usual manner; segments of the desired shape are sketchedupon the article and then filled in with the various colors to a linemade at point of joining to next segments. After the first coat is dry Ipaint in the dividing lines in distinct color, preferably of denseenamel or opaque body and producearaised boundaryline so as to morenearly represent a metallic framing when light is passed through; whenthe article is completed as to the desired decoration of ground work thearticle is placed in a muffle or kiln and fired so as the colors arefluxed or vitrified and permanently attached to the surface; with somecolors and patterns it may be necessary to fire one part of the colorsbefore finishing the complete decoration.

When it is desired to combine a pattern with the ground work, after thefirst application is well dried, parts of the ground work necessary tothe design are cut out by moistening the dried colors with creosote andwiped out leaving a clean surface into which colors are filled in orpainted to form the designs. Where very ornate or intricate designs arerequired several firings may be necessary to complete the decoration soas to thoroughly aifix one color before applying another and so preventtheir fluxing into each other and mar-ring the desired effect.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

As a new article of manufacture, an article of glassware having itssurface ornamented or decorated, and divided into sections by opaquedividing lines, the latter projecting out from the surface of thearticle to give it the appearance of being constructed in secgionlsl ofstained glass, substantially as set ort In testimony whereof I havesigned this specification in the presence of two subscribing witnesses.

ALBERT STEFFIN.
